4.257μm Low Power Benchtop ICL-DFB Tunable Continuous Wave Laser (Benchtop Light Source

4.257μm Low Power Benchtop ICL-DFB Tunable Continuous Wave Laser (Benchtop Light Source

The 4.257μm ICL-DFB laser is a tunable continuous-wave laser developed by IdealPhotonics. It features a narrow linewidth, high power, and low power consumption, making it ideal for gas sensing applications, particularly for testing hydrocarbons and other related gases. Additionally, the benchtop ICL-DFB laser module integrates a driver and temperature control module, and it can be tuned via software to control the laser's temperature and operating current. This ensures stable operation of the laser and maintains the accuracy of the measurement values. The module also includes an FPGA, which facilitates the processing of gas concentration measurements
